Difference Between Brazilian Blowout and Japanese Hair Straightening

Curious about the difference between Japanese hair straightening vs Brazilian blowout?

I totally hear you, it’s definitely a bit confusing!

Don’t worry, I’ll guide you through all of the differences between these two popular methods and help you decide which one is right for you.

Let’s jump right in and get started, shall we?

Brazilian Blowout Vs Japanese straightening; What’s the difference?

The Brazilian blowout is a modern technique that leaves your hair soft and shiny with a natural look and feel.

The method uses keratin proteins that reduce frizz while smoothing out the cuticle layer of each strand.

Sealed within the hair shaft, the keratin becomes impenetrable to humidity, which helps prevent future damage.

You can use this treatment once every 6-8 weeks depending on how often you wash your hair. That’s right! Your style will last up to 4 months with one treatment!  

Brazilian Blowout is the only thermal reconditioning treatment that uses patented ion technology in its formulas.

This amazing technology makes the cuticle in each hair strand lay flat, eliminating that dreaded frizz while sealing in natural moisture.

A Japanese straightening treatment is similar in many ways to the Brazilian blowout, but the end result is different.

The technique is said to have been invented in Japan as a solution for those who had naturally curly or damaged hair that was difficult to maintain.

It involves applying chemicals to your hair that temporarily change its internal structure by increasing its strength, then using an iron or flat iron to achieve straightness.

The main difference between these two treatments is in how long they last.

Both require several hours in the salon.

However, the Brazilian blowout is meant to last for six to eight weeks before needing another round of perms or relaxers.

On the other hand, despite people calling it a “permanent” solution, the Japanese straightening really lasts only one to three months.

Brazilian Blowout is a very popular and cost-effective way of getting your hair straighter. It is definitely my pick for the most innovative and modern method of straightening hair.

The keratin treatment involves using a keratin-based mixture to protect your hair from damage and pollution.

This treatment gives a firm hold on the hair, which lasts for as long as two months when it is carried out.

The Brazilian Blowout only lasts for about three to four months. After that, you need to go for another round of this process.

The procedure of both the treatments is almost similar, and both are carried out at salons.

Yes, this treatment will transform your locks into a sleeker, shinier version and eliminate frizz. It can last up to four months or longer, depending on the condition of your hair and how you take care of it.

Is Brazilian Hair Straightening Is Better Than The Japanese Method?

Brazilian Blowout is better in most cases. The Japanese method can be seriously damaging to hair because it breaks the bonds that hold the strands together. This causes the hair to become dry, brittle, and weak. In turn, your hair becomes unhealthy, causing it to break off at the scalp or split into several hair strands. Many people have switched from Japanese straightening to Brazilian blowout because it is safer for you and makes your hair more beautiful.


Bottom line, in the Japanese hair straightening vs Brazilian Blowout debate, the Brazilian method usually wins because it’s typically gentler to your locks.

However, it really depends on your hair, how long you want the results to last, and other factors that you may not even consider.

That’s why it’s so important to talk to your stylist and ask them what they recommend.
